NemoClaw E2E Fixtures

NemoClaw E2E now has one target execution model, Vitest as the harness and GitHub Actions as the matrix. Vitest owns discovery, filtering, timeouts, reporters, fixture lifecycle, skips, and CI integration. NemoClaw owns the domain layer: target metadata, phase fixtures, product clients, evidence artifacts, redaction, cleanup, expected-state probes, and typed assertion helpers.

The retired typed-shell target runner is documented in RETIREMENT.md. Do not add new durable behavior to the old YAML/bash runner shape.

Direct E2E implementations now live in Vitest. The former test/e2e/test-*.sh entry points have been removed.

Target Model

The typed registry still describes targets as layered metadata:

base environment
  -> onboarding profile / manifest
    -> expected state
      -> optional lifecycle profile
        -> suite metadata for migration tracking

Live execution happens through shared fixtures:

• environment checks CLI/install/runtime readiness.
• onboard performs supported onboarding profiles.
• lifecycle performs supported post-onboard mutations.
• stateValidation probes host-observable expected state.
• artifacts, secrets, cleanup, and shellProbe provide shared fixture services.
• The automatic progress fixture reports the ordered semantic phase plan for each e2e-live case. Normal output contains the target/scenario identity, immediate phase starts and completions, and phase plus total durations. The harness appends release registered E2E resources to cover registered cleanup. After five minutes in one phase, a content-free stall diagnostic adds child-output age, current redacted command or cleanup activity, and runner resources; it repeats every ten minutes while the phase remains active.
• Credential-free integration tests selected by the shared E2E planner use the lightweight workflow-e2e-test fixture for the same progress and artifact contract without depending on the stateful live fixture services.

The test/e2e/fixtures/ path is fixture/support code, not a test harness or runner. Vitest remains the only test harness.

suiteIds remain metadata for reporting and migration planning. They do not dispatch shell validation suites.

How To Run

# List canonical target ids
npx tsx test/e2e/registry/run.ts --list

# Emit the GitHub Actions fan-out matrix payload
npx tsx test/e2e/registry/run.ts --emit-live-matrix

# Emit the matrix for selected target ids
npx tsx test/e2e/registry/run.ts --emit-live-matrix --targets ubuntu-repo-cloud-openclaw

# Fixture/support tests
npx vitest run --project e2e-support --silent=false --reporter=default

# Validate every live test and workflow-selected integration test without running bodies
npm run test:e2e-phases:check

# Opt-in live E2E targets
npm run test:live-e2e -- --silent=false --reporter=default

# Rank one or more downloaded/extracted live artifact directories
npm run test:runtime-audit -- e2e-artifacts/run-1 e2e-artifacts/run-2

The aggregate live command rebuilds the CLI before Vitest starts and runs live test files serially. Live E2E projects do not retry an entire failed test. These tests mutate host, Docker, gateway, and sandbox state, so re-entering one on the same runner can replace the original failure with stale-lock, storage-exhaustion, or ownership noise. A target may retry a transient operation only inside its own cleanup boundary. Retry a full target by starting a fresh workflow run and runner.

During fixture teardown, every passing or failing live test writes test-progress.json beside its other target artifacts. The runtime audit groups those files by target, optional shard, and test name, then reports median, p95, maximum, p95-minus-median variability, and the slowest observed phase with its duration and outcome. Scheduled and ordinary manual workflows publish the current run's table in the GitHub Actions scorecard summary. The summary reads the target identity from E2E_TARGET_ID, falling back to the Actions GITHUB_JOB, and reads NEMOCLAW_E2E_SHARD when set. It retains overall start, finish, and duration, and records each declared or harness-owned phase's start, finish, duration, outcome, child-output event count, and last-output timestamp. Use several recent workflow artifact directories to distinguish a consistently expensive test from a variable one.

Normal phase output repeats the workflow target and test scenario because a long-running Actions step may not expose Vitest's final report yet. It reports the current position and semantic label, total and phase elapsed time, and the outcome when that phase ends:

[e2e target="token-rotation" scenario="rotates a live sandbox credential"] [phase 1/4] started: provision a clean sandbox (total 0s; phase 0s)
[e2e target="token-rotation" scenario="rotates a live sandbox credential"] [phase 1/4] completed: provision a clean sandbox — passed in 48s (total 48s)
[e2e target="token-rotation" scenario="rotates a live sandbox credential"] [phase 2/4] still running: exercise token rotation (total 5m 48s; phase 5m; child output 12s ago; activity command: credential-rotation; ...)
[e2e target="token-rotation" scenario="rotates a live sandbox credential"] [phase 4/4] event: cleanup started: destroy sandbox e2e-token-rotation (total 6m; phase 0s)
[e2e target="token-rotation" scenario="rotates a live sandbox credential"] [phase 4/4] completed: release registered E2E resources — passed in 6s (total 6m 6s)

The still running line first appears after five minutes in the same phase and then every ten minutes. Shell probes update child-output liveness and redacted command activity automatically, but that detail remains hidden until the stall threshold. Automatic child-output observation forwards only the event timestamp and stream name, never the output contents. Use progress.event("literal content-free status") only for immediate semantic events such as an operation timeout, retry cleanup, backoff, or the next attempt. Event labels are logged, so never include child output, request data, credentials, or tokens. For the stateful live fixture, the harness-owned final phase captures registered cleanup duration, failures, and stalls; each registry entry reports a redacted start/outcome event and is shown as the active cleanup operation in a stall heartbeat. Workflow-selected integration tests declare their own final release phase. Soft assertion failures are recorded against the semantic phase where they occurred, while successful resource release retains its own passed outcome.

Every e2e-live test and every credential-free integration test selected by the shared E2E planner must declare two to twelve behavior-specific phases and transition through them in order. For example:

const PHASES = [
  "provision a clean sandbox",
  "exercise token rotation",
  "verify the rotated credential",
] as const;

test(
  "rotates a live sandbox credential",
  { meta: { e2ePhases: PHASES } },
  async ({ progress }) => {
    await provisionSandbox();
    progress.phase("exercise token rotation");
    await rotateCredential();
    progress.phase("verify the rotated credential");
    await verifyCredential();
  },
);

Use phases for meaningful scenario boundaries, not individual commands. Labels must be unique within the plan; generic labels such as setup, execute, verify, and test body are rejected. Pass each phase label as a string literal so the collection-only checker can validate the transition without executing the test body; variables and array lookups are rejected. A phase transition may skip optional intermediate phases, which are recorded with a skipped outcome, but it cannot move backward or select an undeclared label. When a module has multiple tests, including tests with the same phase plan, keep each literal transition inside its owning test callback so the checker can attribute it to that case. A helper may own the operational boundary by accepting a callback that performs the transition. Completed phases use passed, failed, or skipped outcomes. A passing path must enter the final declared phase before returning, or fixture teardown fails the test. In e2e-live, do not declare or enter release registered E2E resources; the stateful harness appends and enters it automatically after the test's phase plan. Workflow-selected integration tests own and enter their final release phase. npm run test:e2e-phases:check collects every e2e-live module plus the workflow-selected integration modules from the authoritative shared-job plan. It rejects missing or invalid plans without executing test bodies. Live modules must import fixtures/e2e-test.ts; selected integration modules must import fixtures/workflow-e2e-test.ts and declare their final release phase explicitly. The same check audits direct child-process boundaries reachable through shared E2E helpers. Prefer ShellProbe; a long-lived process that cannot use it must live in an explicitly audited progress-aware boundary, close its activity on exit, and report child output only as { stream, atMs }. Blocking child-process calls require a positive timeout shorter than the first heartbeat plus killSignal: "SIGKILL", so that timeout cannot be ignored. Raw output belongs only in redacted artifacts.

Audited subprocess helpers require the fixture-provided frozen, canonical progress capability. Forward that exact object unchanged instead of copying it or constructing a look-alike or no-op adapter. A module-private brand, runtime registry, frozen-object check, type system, and semantic checker enforce this boundary.

Progress callbacks are diagnostic-only: callback failures must not change command execution, test outcomes, or registered resource release.

The retired --emit-matrix and --plan-only paths must not be reintroduced.

When adding or changing a live test, update test/e2e/mock-parity.json with the fast PR-collected test that covers its mockable contract. If the behavior cannot be reproduced without real infrastructure, record a concise liveOnlyReason instead. The PR and main CLI coverage shards enforce this changed-file policy alongside the e2e-support project without requiring an immediate backfill of untouched tests.

CI Entry Points

• tools/advisors/risk-plan.mts is the small deterministic selection policy shared by PR Review Advisor and the PR E2E controller. It maps changed runtime surfaces to invariant families and canonical e2e.yaml jobs; it is not a second test runner or migration-status ledger. The advisor uses it as recommendation context, while the controller applies it independently without model output.

• .github/workflows/pr-e2e-gate.yaml reserves the internal E2E / PR Gate Coordination check for every PR SHA, including forks, before CI / Pull Request completes. Its default-branch pull_request_target path also publishes the native GitHub Actions job named E2E / PR Gate. The read-only observer runs from github.workflow_sha, validates the live PR head and base, waits for the matching trusted coordination identity, and mirrors the terminal verdict into the required job. Its summary is static, while the job log includes the validated trusted controller-run link. Authorization states remain pending while the maintainer decision is recorded. During rollout, the observer also accepts the former E2E / PR Gate custom-check name for the same PR/base SHA identity. The controller builds the risk plan from GitHub's complete file list. Internal revisions normally dispatch every selected job and verify each expected risk-signal.json; this remains automatic when their e2e-control-plane matches are drawn only from the trusted controller workflow and scripts. Other or mixed internal control-plane revisions require a maintainer-authorized run for the PR SHA; only its verified evidence can pass coordination. Risky forks require protected approval before the trusted workflow runs their exact repository and SHA with E2E credentials. See NemoClaw E2E CI for the full lifecycle.

• .github/workflows/e2e.yaml runs selected or all supported live E2E targets and uploads an explicit artifact allowlist with JSON summaries plus action, log, and shell command-evidence directories under 14-day retention. Final OpenShell gateway-auth artifacts pass a fail-closed safety scan after cleanup. The scanner copies safe files into a private staging directory, scans that copy again, and adds a marker bound to the current Actions run ID and attempt. Unsafe source files are quarantined or deleted. The workflow uploads only the staged copy, so later changes to the source directory cannot alter the approved payload. The allowlist includes each target's sanitized onboard timing summary at e2e-artifacts/live/<target>/cloud-onboard-trace-timing-summary.json. Raw onboard traces stay under the runner temporary directory and are deleted before artifact upload. These per-target timing summaries are artifact evidence only. The Slack and GitHub scorecard timing comparison remains scoped to the dedicated cloud-onboard artifact. PR E2E dispatches authenticate the controller-owned coordination check before checking out the PR revision, then validate the PR SHA and controller metadata before preparation. Direct manual dispatches cannot reuse the PR input shape to run fork code. Selected runs attach test/e2e/risk-signal-reporter.ts to live Vitest invocations and suppress PR reporting and scorecards. The workflow boundary requires every selected job shard to upload its evidence artifact.

• .github/workflows/platform-vitest-main.yaml runs the full Vitest suite in four independent shards on each of macOS and WSL, with fail-fast disabled. Each macOS shard installs the pinned OpenShell formula and has a 30-minute budget. Each WSL shard has a 90-minute budget, and WSL runs its additional root-required contracts on shard 1 only. .github/workflows/e2e-branch-validation.yaml, macos-e2e.yaml, wsl-e2e.yaml, and regression-e2e.yaml call focused E2E targets directly for their E2E coverage. Individual repository-hosted targets, including ollama-auth-proxy, are selected through .github/workflows/e2e.yaml.

• vitest.config.ts contains e2e-support for fast fixture/support tests and e2e-live for opt-in live target execution. The PR and main CLI coverage shards include e2e-support for code changes; they never opt into live targets.

Migration Tracking

Migration status is tracked outside the repository. GitHub issues and pull requests are the source of truth for script-by-script state, ownership, replacement E2E coverage, and retirement decisions.

GitHub issues and PRs own changing migration status. The key issues are:

• #3588: parent layered E2E architecture epic
• #4941: Vitest fixtures as the target execution model
• #4990: phase fixtures and registry-driven live discovery
• #5098: direct former bash-suite migration epic

The former repo-local migration ledger and generated assertion inventories are removed because they duplicated live GitHub state and drifted quickly. The durable guardrails are workflow contract tests and source-shape checks that verify CI calls Vitest directly and the removed shell suite does not come back.

Prefer new E2E coverage in Vitest fixtures. When shell, installer, process, platform, or full user-flow behavior is the contract, invoke that real boundary from the E2E test rather than preserving a second durable runner.
